[nabeelakram436]

Hi, I have a Toshiba Satellite L50 here and its not powering up.

Bought from guy who has no need of bricked laptop

It would give a Power LED and a Charge LED but press the power on button and nothing not even a fan noise or anything.

Tried removing all hardware still nothing

Left the battery on charge all day, the next day it was only reading 3 volts.

Removed battery and still not even a power or charge indicator.

Mains charger giving 19 volt

Can some one suggest how to fix it , I have swapped power packs and Ram.

Review the charger sticky above by piernov.

The fault will often be in the dcin mosfets that get damaged. To get started, link the schematics for your laptop if they are available. Check the schematics forum of this website and then share the link only here. With a meter and steady hands, should be able to diagnose the laptop.

Post a few pics of your logic board. We need to review the location of the parts to determine which version is inside of your laptop.

Perhaps the logic board is like the attached view? If the laptop is popular enough, there will be leaked schematics and a boardview file to assist us. Otherwise, the process will take longer to diagnose. In general, there is the power adapter -> DCin mosfets (usually are 2 of these) -> then the charger IC. Most of the time, the fault is in this region of the logic board.

Using a meter and hot air soldering tools, it is possible to repair most of these boards. If required, you can lean on your local cell phone repair store to make the replacement of the defective parts after a review.
